China is reportedly looking to line up other countries against the U.S. in a pending trade war after the White House took an unexpected move forward on tariffs a day earlier, the Wall Street Journal said Wednesday, citing Chinese officials.

On Tuesday, the White House announced it would have a final list of $50 billion in imports that would be subject to 25 percent tariffs by June 15, and two weeks later would announce investment restrictions on Chinese acquisitions of U.S. technology.

In response, China is reportedly looking to line up countries against the U.S., the Journal reported. The countries in question are mostly in Europe and Asia, where companies could benefit from China’s plans to give foreign companies more open access to its markets.

Tuesday’s announcement came just days after the two countries announced a tentative solution.
